Muon Space vs SITAEL: Platforms compared

Scores, Space (of 10)

Darker bar: ahead of the other company on that measure.

Positioning

Muon Space is a US satellite maker (founded by ex-SpaceX engineer Jonny Dyer) built on a full-stack Mission Foundry model, with 11 satellites flown and a San Jose plant targeting 500 satellites a year by 2027. It raised a $250M Series C in August 2026 at a $1.5B valuation (Eclipse-led, with Google, Salesforce Ventures, and Woven/Toyota), launched the first three operational FireSat wildfire-detection satellites with Google in July 2026, and debuted a higher-power platform aimed at orbital data centers (pathfinder 2028). Revenue, FireSat economics, and the 500-per-year credibility are open.
